Suspected Charlie Kirk shooter Robinson booked on aggravated murder, expected to be charged Tuesday

Suspected Charlie Kirk shooter Tyler Robinson is expected to be charged with aggravated murder, felony discharge of a firearm causing serious bodily injury, and obstruction of justice.

Robinson, a 22-year-old Utah resident, allegedly shot Kirk, a 31-year-old conservative political activist, on Wednesday from about 150 yards away with a high-powered rifle at Utah Valley University, in Orem, Utah. Kirk was taken to a hospital, where he died from the gunshot wound.

"Based on the evidence detailed in this statement, I believe there is probable cause that Tyler Robinson committed the crimes of aggravated murder by shooting Charlie Kirk in a circumstance that put many around him at grave risk of death, felony discharge of a firearm, and obstruction of justice for moving and hiding the rifle believed to be used in the shooting," an officer wrote in a probable cause affidavit, Fox News reported.

Utah County attorney Jeff Gray plans to file charges on Tuesday, with Robinson's first court appearance to be at 3 p.m. that day, according to TMZ.

A source told Fox News that Robinson could face federal charges on Friday.
